[0026] The vibrator 2 is arranged on the outer bottom wall of the polishing bowl 1 and can drive the polishing bowl 1 to vibrate. The inner wall of the polishing bowl 1 is provided with an elastic rubber pad layer. The inner cavity of the polishing bowl 1 is used to place polishing abrasives and chip capacitors. The springs 3 are provided in plurality and are connected between the connecting bottom plate 4 and the bottom of the polishing bowl 1. The upper side wall of the polishing bowl 1 is provided with a rotating shaft 11 symmetrically arranged on the left and right. The support frame 5 is provided on the base 8. The top of the support frame 5 is provided with a U-shaped groove 51 that rotates with the rotating shaft 11. The vertical locking device 6 is provided on the base 8.

When the capacitor polishing device is feeding, the opening of the polishing bowl 1 faces upward; when the capacitor polishing device is unloading, the opening of the polishing bowl 1 faces downward.

[0029] Exemplarily, the vertical locking device 6 includes a plurality of lifting cylinders, the cylinder bodies of the lifting cylinders are mounted on the base 8, so that the vertical locking device 6 is stably connected to the base plate 4 for support. Preferably, a groove is provided on the connecting base plate 4 to cooperate with the end of the rod body of the lifting cylinder; specifically, when the capacitor polishing equipment is polishing, the rod body of the lifting cylinder extends out and lifts up the connecting base plate 4; when the capacitor polishing equipment is feeding or unloading, the rod body of the lifting cylinder retracts and separates from the connecting base plate 4.

[0030] Exemplarily, a positioning cylinder 9 electrically connected to the controller is provided in the middle of the support frame 5. When the capacitor polishing device is feeding, the rod of the positioning cylinder 9 extends out, and the side wall of the polishing bowl 1 is abutted against the side wall of the rod of the positioning cylinder 9.

[0031] Furthermore, the capacitor polishing equipment also includes a vertical position sensor electrically connected to the controller, the vertical position sensor includes a vertical position transmitting end arranged on the side wall of the polishing bowl 1 and a vertical position receiving end arranged on the support frame 5, when the vertical position receiving end detects the vertical position transmitting end, the polishing bowl 1 is in a vertical state, so that when the polishing bowl 1 is vertically in place, the vertical position sensor feeds back the information that the polishing bowl 1 is vertically in place to the controller, the controller starts the vertical locking device 6 so that the vertical locking device 6 lifts up the connected bottom plate 4, starts the positioning cylinder 9 so that the cylinder body of the positioning cylinder 9 extends, and pauses the winding device 7 to ensure the accuracy of the position of the polishing bowl 1 during polishing.

[0032] Furthermore, the capacitor polishing equipment also includes a tilt-in-place sensor electrically connected to the controller, the tilt-in-place sensor includes a tilt-in-place transmitting end arranged on the side wall of the polishing bowl 1 and a tilt-in-place receiving end arranged on the support frame 5, when the tilt-in-place receiving end detects the tilt-in-place transmitting end, the polishing bowl 1 tilts to a preset tilt angle value; the tilt-in-place sensor feeds back information that the polishing bowl 1 is tilted in place to the controller, and the controller pauses the winding device 7 to ensure that the position of the polishing bowl 1 is accurate when feeding.

[0033] Furthermore, the capacitive polishing equipment also includes a bowl in place sensor electrically connected to the controller, the bowl in place sensor includes a bowl in place transmitting end arranged on the rotating shaft 11 and a bowl in place receiving end arranged in the U-shaped groove 51, when the bowl in place receiving end detects the bowl in place transmitting end, the rotating shaft 11 is placed in the U-shaped groove 51, and after ensuring that the rotating shaft 11 of the polishing bowl 1 and the U-shaped groove 51 of the support frame 5 are accurately in place, the controller starts the winding device 7 to wind up the traction rope 71, thereby gradually tilting the polishing bowl 1.

[0034] Specifically, the elastic rubber pad layer is a 8 mm thick polyurethane layer, which is wear-resistant and has a certain elasticity, effectively protecting the chip capacitor and extending the service life of the polishing bowl 1. Preferably, the polishing abrasive includes at least one of abrasives, polishing powder and sandpaper, which can be arbitrarily combined according to actual needs.

[0035] Exemplarily, the inner wall of the polishing bowl 1 is an arc surface, so that when the vibrator 2 vibrates, the chip capacitor and the polishing abrasive in the polishing bowl 1 continuously roll, thereby reducing polishing dead angles.

[0036] In summary, the present invention cooperates with the vibrator 2 and the spring 3 to make the polishing bowl 1 suspended on the spring 3 repeatedly vibrate from the inside to the outside, so that the chip capacitor and the polishing abrasive in the polishing bowl 1 roll, so as to achieve the purpose of polishing and grinding the chip capacitor end, make the chip capacitor metal end smoother and flatter, reduce metal nodules and metal impurities on the surface of the chip capacitor, make the chip capacitor metal end tighter, reduce the voids in the metal end, and improve the qualified rate of the chip capacitor; the elastic rubber pad layer can reduce the damage of the chip capacitor caused by the polishing bowl 1 during the polishing process; by tilting the polishing bowl 1, the feeding equipment can feed the polishing abrasive and the chip capacitor into the inner wall of the polishing bowl 1, and the winding device 7 releases the traction rope 71 to return the polishing bowl 1 from the inclined state to the vertical state, so that the polishing abrasive and the chip capacitor slowly fall from the inner wall of the polishing bowl 1 to the bottom of the polishing bowl 1, avoiding damage to the chip capacitor and improving the degree of automation and work efficiency.
